Oregon does not allow common law marriages to be formed within the state, but courts will recognize and dissolve valid common law marriages established in other states under the Full Faith and Credit Clause. If you entered a common law marriage in Colorado, Texas, Kansas, Iowa, Montana, Oklahoma, Utah, or the District of Columbia, Oregon circuit courts have full authority to grant a divorce with the same $287-$301 filing fee and equitable distribution principles applied to all Oregon dissolutions. Couples who cohabitated in Oregon without a valid out-of-state common law marriage have no divorce rights and must resolve property disputes through contract law, with median litigation costs of $15,000-$30,000.

Oregon Does Not Create Common Law Marriages

Oregon is one of 13 states that has never recognized common law marriage formation within its borders. No amount of cohabitation time, regardless of whether you lived together for 5 years, 20 years, or longer, creates a legal marriage in Oregon. Under Oregon law, a valid marriage requires obtaining a marriage license from a county clerk and solemnizing the marriage before an authorized officiant per ORS 106.150. Without these formal requirements, couples remain legally unmarried with no automatic property division rights upon separation.

This distinction carries substantial financial consequences. Married couples divorcing in Oregon benefit from equitable distribution under ORS 107.105(1)(f), which presumes both spouses contributed equally to property acquired during marriage. Unmarried cohabitants must instead prove ownership through title documents, written agreements, or implied contracts, with the burden of proof falling entirely on the claimant. The Oregon Supreme Court established in Beal v. Beal, 282 Or. 115 (1978), that courts should distribute property of unmarried couples based on express or implied intent, but this requires expensive litigation averaging $15,000-$30,000 to resolve compared to typical uncontested divorce costs of $1,500-$5,000.

Divorcing a Common Law Marriage from Another State in Oregon

Oregon circuit courts will grant divorces for valid common law marriages established in the eight jurisdictions that currently recognize them: Colorado, Texas, Kansas, Iowa, Montana, Oklahoma, Utah, and the District of Columbia. Under the Full Faith and Credit Clause of the U.S. Constitution, Oregon must respect marriages validly formed in other states, even though Oregon itself does not allow common law marriage formation. The divorce process follows identical procedures to any Oregon dissolution, with the same filing fees of $287-$301 and equitable distribution principles.

Requirements to Prove Your Out-of-State Common Law Marriage

Before Oregon courts will dissolve your common law marriage, you must establish that a valid marriage existed under the originating state's law. Courts typically require documentation including affidavits from both parties, third-party witness statements, joint tax returns filed as married, shared bank account records, insurance beneficiary designations, and evidence you held yourselves out publicly as spouses. The specific requirements vary by originating state:

StateKey RequirementsEvidence Needed
ColoradoMutual intent + conduct as spousesThird-party affidavits, joint accounts, tax returns
TexasAgreement + cohabitation + public representationDeclaration of Informal Marriage or witness testimony
KansasPresent-tense agreement + cohabitation + holding outBoth parties age 18+, written statements
IowaIntent + continuous cohabitation + public declarationJoint property, shared finances documentation
MontanaMutual consent + cohabitation + reputationNo minimum duration, community recognition
OklahomaAgreement + cohabitation + holding outBoth competent, not already married
UtahConsent + legal capacity + cohabitation + public reputationCourt or administrative order recommended
District of ColumbiaAgreement + cohabitation + community recognitionNo ceremony required, witness testimony

Texas offers a streamlined proof method through the Declaration of Informal Marriage, which can be filed with any county clerk for approximately $46 and provides official documentation of the marriage. Colorado courts look at the totality of circumstances under the framework established in In re Marriage of Hogsett & Neale, 478 P.3d 713 (2021), examining factors like shared last names, joint finances, and referring to each other as spouses.

Oregon Residency Requirements for Common Law Divorce

Under ORS 107.075, Oregon applies a two-tier residency requirement depending on where your marriage (including common law marriage) was formed. If the common law marriage was established in Oregon (which is legally impossible, so this scenario applies only to ceremonial marriages performed here), either spouse may file immediately without any waiting period. If the common law marriage was established outside Oregon (the only possibility for common law marriages), at least one spouse must have resided in Oregon continuously for 6 months before filing.

Residency can be established through an Oregon driver's license, voter registration, utility bills in your name, lease or mortgage documents, state tax returns showing an Oregon address, or employment records. Non-immigrant alien status does not prevent establishing Oregon domicile for dissolution purposes. Once residency is established, you may file in the circuit court of any county where either spouse resides.

Filing Fees and Court Costs

The Oregon circuit court filing fee for dissolution of marriage is $287 effective January 1, 2026, under ORS 21.155, though some counties charge up to $301. Beyond the initial filing fee, expect additional costs including process server fees ($30-$150), certified copies of the judgment ($5-$25 each), parent education classes if children are involved ($60-$100 per person), and mediation fees if ordered ($100-$300 per hour).

Fee waivers are available for petitioners whose household income falls at or below 125% of the federal poverty level, which is $19,506 for a single person in 2026. Recipients of SNAP, TANF, or SSI benefits also qualify. With a fee waiver, your only out-of-pocket cost is typically $50-$150 for service of process.

Total Cost Breakdown

Divorce TypeEstimated Cost Range
Uncontested (self-filed)$301-$500
Uncontested (with attorney)$1,500-$5,000
Contested (average)$15,000-$30,000
Contested (complex, high-asset)$50,000+
With fee waiver$50-$150 (service only)

As of May 2026, verify the exact filing fee amount with your local circuit court clerk before filing.

Property Division in Common Law Divorce

Oregon applies equitable distribution principles to all divorces, including those dissolving out-of-state common law marriages. Under ORS 107.105(1)(f), courts divide property as may be just and proper in all the circumstances, with a rebuttable presumption that both parties contributed equally to property acquired during the marriage. This presumption treats homemaker contributions as equal to financial contributions, meaning a spouse who did not work outside the home still receives equal consideration.

Equitable distribution does not necessarily mean 50/50. Courts weigh factors including marriage length, each spouse's earning capacity, financial and non-financial contributions, tax consequences of the proposed division, children's needs, and the health of both parties. Oregon is a pure no-fault state, so marital misconduct plays no role in property division. For long marriages (typically 10+ years), courts generally award near-equal splits, though divisions of 60/40 or other ratios are possible based on specific circumstances.

Separate vs. Marital Property

Marital property includes all assets and debts acquired during the common law marriage, regardless of which spouse's name appears on the title. Separate property, including assets owned before the marriage, inherited property, and gifts received individually, is generally excluded from division. However, if separate property was commingled with marital assets or significantly appreciated due to either spouse's efforts during the marriage, courts may include some or all of it in the equitable distribution.

Retirement accounts and pensions are explicitly classified as divisible property under ORS 107.105. ERISA-governed plans require a Qualified Domestic Relations Order (QDRO) for division, while Oregon PERS accounts use separate division forms specific to state retirement systems.

No Common Law Marriage Alternative: Property Rights for Unmarried Couples

Couples who cohabitated in Oregon without a valid common law marriage from another state cannot file for divorce and have no automatic property rights upon separation. Oregon law treats unmarried cohabitants fundamentally differently than married couples, with property belonging to whoever holds title unless there is a written agreement or the other party can prove an implied contract.

The Oregon Supreme Court's Beal v. Beal decision established that courts should distribute property of unmarried couples based on express or implied intent, but this requires litigation. Without a written or oral agreement, courts examine the intent of the parties regarding each asset and liability. This process typically costs $15,000-$30,000 in attorney fees and court costs, compared to $1,500-$5,000 for an uncontested divorce with an attorney.

No Spousal Support for Unmarried Partners

Unlike married couples dissolving through divorce, unmarried partners in Oregon have no legal right to spousal support (alimony) upon separation. This distinction applies regardless of relationship length or financial disparity between partners. A partner who sacrificed career advancement to support the household receives no automatic compensation under Oregon law if the couple was never legally married.

Registered Domestic Partnerships in Oregon

Oregon offers registered domestic partnerships as an alternative to marriage under ORS 106.300 through ORS 106.340. Under the Oregon Family Fairness Act, a registered domestic partnership is a civil contract between two individuals who are at least 18 years old, otherwise capable of marriage, and with at least one partner being an Oregon resident. Importantly, only same-sex couples can currently file for registered domestic partnerships in Oregon.

Under ORS 106.340, any privilege, immunity, right, or benefit granted to a married individual extends on equivalent terms to an individual in a domestic partnership. This includes authority to make medical decisions, inheritance protections without a will, and access to dissolution procedures identical to divorce. Partners in a domestic partnership who wish to separate must file for dissolution through the circuit court, following the same process and paying the same $287-$301 filing fee as married couples.

Dissolution of Domestic Partnerships

Each individual who signs a Declaration of Domestic Partnership automatically consents to Oregon circuit court jurisdiction for dissolution proceedings, even if one or both partners later move out of state. The petition may be filed in the county where either partner last resided. Property division follows the same equitable distribution principles as divorce, and partners cannot file a new Declaration of Domestic Partnership or enter a marriage with someone else until a dissolution judgment is entered.

Cohabitation Agreements: Protecting Unmarried Couples

For unmarried couples who cannot establish a common law marriage (the vast majority in Oregon), a cohabitation agreement provides crucial legal protection. Similar to a prenuptial agreement, a cohabitation agreement is a written contract that outlines each partner's rights and responsibilities regarding property ownership, financial obligations, and procedures for dividing assets if the relationship ends.

A comprehensive cohabitation agreement typically addresses joint property purchases (especially real estate), shared bank accounts and investments, debt responsibility, household expense allocation, business interests, and separation procedures. Attorney fees for drafting a cohabitation agreement typically range from $500-$2,500 depending on complexity, a fraction of the $15,000-$30,000 average cost of litigating property disputes without an agreement.

States That Recognize Common Law Marriage (2026)

Only eight jurisdictions currently allow new common law marriages to be formed. If you established a common law marriage in one of these locations before moving to Oregon, Oregon courts will recognize your marriage for divorce purposes:

JurisdictionKey RequirementsSpecial Notes
ColoradoMutual intent + conduct as spousesNo minimum cohabitation period
TexasAgreement + cohabitation + public representationDeclaration of Informal Marriage available ($46)
KansasPresent agreement + cohabitation + holding outBoth parties must be 18+
IowaIntent + continuous cohabitation + public declarationNo specific duration required
MontanaMutual consent + cohabitation + reputationRecognized since territorial days
OklahomaAgreement + cohabitation + holding outBoth parties competent and unmarried
UtahConsent + legal capacity + cohabitation + reputationCourt or administrative validation recommended
District of ColumbiaAgreement + cohabitation + community recognitionFederal district, not a state

Several states previously recognized common law marriage but no longer allow new formations: Alabama (ended 2017), Georgia (ended 1997), Pennsylvania (ended 2005), South Carolina (ended 2019), Florida (ended 1968), Indiana (ended 1958), and Ohio (ended 1991). Common law marriages validly established in these states before their cutoff dates remain legally valid and would be recognized by Oregon courts.

Timeline for Common Law Divorce in Oregon

Oregon eliminated its 90-day waiting period in 2011, meaning divorce can finalize immediately upon the judge signing the judgment if all issues are resolved. However, realistic timelines depend on case complexity:

ScenarioTypical Timeline
Uncontested (all issues agreed)30-90 days
Contested (negotiated settlement)6-12 months
Contested (trial required)12-24 months
Complex (high assets, custody disputes)18-36 months

For common law divorces specifically, additional time may be needed to establish that a valid common law marriage existed under the originating state's law. This proof process can add 1-3 months if documentation is readily available, or 6+ months if contested.

Frequently Asked Questions

Does Oregon recognize common law marriage after 7 years of living together?

No. Oregon does not recognize common law marriage regardless of how long you live together, whether 7 years, 20 years, or longer. There is no duration of cohabitation that creates a legal marriage in Oregon. The 7-year myth has no basis in any state's law. You must obtain a marriage license and have a ceremony performed by an authorized officiant to be legally married in Oregon.

Can I get divorced in Oregon if I had a common law marriage in Texas?

Yes. Oregon courts will dissolve common law marriages validly formed in Texas under the Full Faith and Credit Clause. You must meet Oregon's 6-month residency requirement and prove the Texas common law marriage existed by showing: (1) you agreed to be married, (2) you lived together in Texas as spouses, and (3) you held yourselves out publicly as married. A Texas Declaration of Informal Marriage ($46) provides the strongest proof.

How do I prove my common law marriage from another state in Oregon court?

Oregon courts accept various forms of evidence including joint tax returns filed as married filing jointly, affidavits from both parties, third-party witness statements, shared bank account records, insurance policies listing each other as spouses, and property titled jointly as husband and wife. The specific requirements depend on the state where the common law marriage was formed. Gathering comprehensive documentation before filing saves time and reduces legal costs.

What are the alternatives to common law marriage in Oregon?

Oregon offers registered domestic partnerships for same-sex couples under ORS 106.310, providing equivalent rights to marriage. For all couples, cohabitation agreements function like prenuptial agreements for unmarried partners, outlining property rights and separation procedures. Attorney fees for drafting a cohabitation agreement typically range from $500-$2,500, substantially less than the $15,000-$30,000 average cost of litigating property disputes without an agreement.

How is property divided if we were never legally married in Oregon?

Without a valid marriage or domestic partnership, Oregon courts do not apply divorce property division rules. Property belongs to whoever holds title unless you have a written cohabitation agreement or can prove an implied contract. The Oregon Supreme Court ruled in Beal v. Beal (1978) that courts should distribute unmarried couples' property based on express or implied intent, but proving intent requires litigation that averages $15,000-$30,000 in legal costs.

Can unmarried partners get spousal support in Oregon?

No. Oregon law does not provide spousal support (alimony) for unmarried partners, regardless of relationship length or financial circumstances. This applies even if one partner gave up career opportunities to support the household. Only legal spouses or registered domestic partners may seek spousal support through Oregon dissolution proceedings. A cohabitation agreement can create contractual support obligations, but this requires advance planning.

What is the filing fee for divorcing a common law marriage in Oregon?

The Oregon circuit court filing fee for dissolution is $287 under ORS 21.155, though some counties charge up to $301. This is the same fee for all divorces, whether from ceremonial or common law marriages. Fee waivers are available for households earning at or below 125% of federal poverty level ($19,506 for a single person in 2026) or receiving SNAP, TANF, or SSI benefits.

How long does a common law divorce take in Oregon?

Oregon has no mandatory waiting period (eliminated in 2011), so uncontested divorces can finalize in 30-90 days once filed. Common law divorces may take 1-3 additional months to prove the out-of-state marriage existed if documentation is readily available. Contested divorces typically take 6-24 months depending on complexity. High-asset cases or those with custody disputes can extend to 18-36 months.

Does moving to Oregon end my common law marriage from another state?

No. A valid common law marriage does not end simply by moving to a non-recognition state like Oregon. Under the Full Faith and Credit Clause, Oregon must recognize marriages validly formed in other states. Your common law marriage remains legally valid until dissolved through formal divorce proceedings. You retain all rights and obligations of marriage, including property division and potential spousal support entitlements.

Can same-sex couples have common law marriages recognized in Oregon?

Yes. Following the U.S. Supreme Court's decision in Obergefell v. Hodges (2015), same-sex couples can form common law marriages in states that recognize them (Colorado, Iowa, etc.) and have those marriages recognized in Oregon. Same-sex couples can also register for domestic partnerships in Oregon under ORS 106.310, which provides equivalent rights to marriage including access to dissolution proceedings with the same $287-$301 filing fee.
